Unformatted text preview: ECE201 Lect-7 1 Circuits with Resistor Combinations (2.6, 8.7) ECE201 Lect-7 2 Solving Circuits with Series and Parallel Combinations • The combination of series and parallel impedances can be used to find voltages and currents in circuits. • This process can often yield the fastest solutions to networks. • This process may not apply to complicated networks. ECE201 Lect-7 3 Series and Parallel Impedances • Impedances are combined to create a simple circuit (usually one source and one impedance), from which a voltage or current can be found • Once the voltage or current is found, KCL and KVL are used to work back through the network to find voltages and currents.
